The tubea has its lower centrally with a depending lug 13, which has portionscrew-threaded internally to render a vertically-arranged screw-threadedhole 14, too 50 it capable of being screwed onto a gas-supengaged by thecorrespondingly threaded ply pipe. (Notshowm) The tubeaisformed shank ofa screw h, which extends through end of the chimney-holder.

the top of the drumfand has its head abutting against the under side ofthe said top. The screw it consequently holds the head 9 down upon thedrumf. An annular space is formed, therefore, around the lug 13, whichchamber is in open relation around the upper end of the drum f with thespace between the drum and the surrounding wall or walls of themixing-chamber e.

The head g is provided with four upwardlydischarging andupwardly-projecting tubular projections or nozzles Z, having thepassage-ways therethrough preferably round and in open relation with thespace 70. The projections or nozzles Z are arranged, preferably,equidistant apart around and equidistant from the center of the head g.

The drumf is large enough at its upper end to extend in under the wholeof all of the passage-ways extending through the projections or nozzlesZ, and preferably a washer m, of fireproof material-such, for instance,as asbestosis interposed between the head of the screw it and the underor inner side'of the top of the drumf.

The tube 0 extends a suitable distance below the tube d, as alreadyindicated, and has its lower end enlarged transversely, as at 15, andsurrounding the gas-discharging nose or nozzle b. The external annularshoulder 16,

formed at the upper end of the lower en-' larged portion 15 of the tube0, is perforated, preferably, so as to form several air-inlets 17,arranged at equal intervals around the said tube and dischargingdownwardly into the said portion 15 of the tube.

A chimney-holder r surrounds the tube d externally of the standards Sandis provided at its lower end with inwardly projecting arms 18, which areriveted or otherwise secured to the said standards, and suitably-appliedbraces t extend between the lower end of the casing of the chamber e andthe lower A globe, glass, or chimney u is shown within the chimneyholderand surrounds the burner in the usual manner.

The chimney-holderrbearsamantle-holder 00, which is usually a rod orwire extending upwardly into the chimney, and the mantle 3 which is tobe rendered incandescent, is sus pended from the upper end of themantleholder and has its lower end embracing the upper end of'the casingof the chamber e.

In the operation of the burner the air which supplies the oxygennecessary to produce proper combustion passes into the lower end of-thetube 0, and the gas is discharged by the nozzle 22 into the said end ofthe tube a, and the gas is discharged by the nose or nozzle 1) into thelower end of the tube 0. The air which enters the tube 0 is largelysupplied through the air-inlets l 7, and generally air also enters thesaid tube at its lower end. The air and the gas pass upwardly throughand commiugle more or less within the tube a and are discharged by thelatter upwardlyinto the drum f, wherein the gas and the air morethoroughly commingle, and the resulting combustible and inflammablemixture passes from within the drum through the numerous perforations inthe top and sides of the drum into the space surrounding the drum andinto the annular space It next above the drum; but all of the mixturedischarged from the drum finds its wayinto the space 7e and is uniformlydistributed bythe latter to the tubular projections or nozzles l, at theouter ends I of which the mixture upon ignition burns with perfectcombustion. It will be observed also that the upward enlargement of thedrum results in a compression of the mixture passing upwardly externallyof the drum.

The endwise adjustability of the tube 0 enables the regulation of thedistance between the air-inlets l7 and the gas-discharging nose ornozzle 5 and also the opening at the lower end of said tube around thesaid nose or nozzle, and it has been found that the volume of airsupplied in advance of the gas-supply nozzle must be decreased orincreased in order to obtain perfect combustion, according as thedensity of the atmosphere increases or decreases. The velocity of theflow of gas into the tube 0 is retarded by an increase in the density orsupply of air in advance of the gas-supply orifice or passage-way. Theimportance therefore of the endwise adjustability of the tube 0 isobvious. Hence it will be observed that the tube 0 after it has beenaddensity is shifted endwise in therequired direction by properlymanipulating the said tube when the atmosphere changes in density, andthe required proportions of air and gas to produce thedesired-combustion are readily obtainable by properly adjusting the tube0 upon lighting the burner and observthe burner.

A bluish or a whitish flame can be produced at pleasure, and thearrangement of the parts are such that the air-supply cannot be reducedto such an extent as to result in the production of a flame that is notsmokeless. In other words, the arrangement of parts is such that whenthe tube 0 is shifted into its lowermost position against the tube or.enough air will still be supplied through the air-inlets l7, and theproportions of air and gas will not be aifected to such an extent as toresult in a smoky flame during the operation of the burner. It will beobserved also that as the gassupply nozzle is surrounded by the tube 0and the air-receiving openings of the said tube are arranged above andbelowthe discharging end of the said nozzle a draft or current of airstraight across the interior of the said tube at the said end of thesaid nozzle is rendered impossible. The lower enlarged portion 15 of thetube 0 forms, therefore, not only the receiving end of the said tube,but constitutes a guard which prevents the creation of such a draft orcurrent without interfering justed as required for an atmosphere ofgivening the character of the flame issuing from It will be observedflames into the burner during the operation of the burner.
